Aluminum substrates are generally stored in a dark, dry environment. Most aluminum substrates are prone to moisture, yellowing, and blackening. Generally, it is used within 48 hours after opening the vacuum packaging.

Compared with the traditional FR-4, the aluminum can minimize the thermal resistance, and the aluminum substrate has excellent thermal conductivity. Compared with the thick film ceramic circuit, its mechanical properties are extremely excellent. In addition, aluminum substrates have the following unique advantages: Meet RoHs requirements; More suitable for SMT process; Extremely effective treatment of thermal diffusion in the circuit design, thereby reducing module operating temperature, extending service life, increasing power density and reliability; Reduce the assembly of heat sinks and other hardware (including thermal interface materials), reduce product size, reduce hardware and assembly costs; optimize the combination of power and control circuits; Replaces fragile ceramic substrates for better mechanical durability

Aluminum circuit boardsis a metal-based copper clad plate with good heat dissipation function. Generally, the single layer is composed of three-layer structure, which is a circuit layer (copper foil), an insulating layer and a metal base layer. Also used for high tech use is designed as double layers, the structure is circuit layer, insulation layer, aluminum base, insulation layer, circuit layer. A very small number of applications are multi-layer boards, which can be made of ordinary multi-layer boards combined with an insulating layer and an aluminum base.
